摘要
统计分析13份苎麻地方品种7个主要农艺性状的变异系数、相关系数和遗传进度。结果表明,各性状三季麻的遗传方差、环境方差及遗传力均有一定的差异。单蔸干麻重、鲜皮厚度、鲜皮出麻率是较重要的产量性状。由于各性状间的遗传相关极为密切,遗传力和遗传进度又各有差异,因此对各性状的选择要综合兼顾,同时在苎麻育种工作中,为了缩短育种年限,应积极开展除常规育种法外的其它育种方法的研究。
Variation coefficient, correlated coefficient and genetic progress of 7 agronomic characters of 3 local ramie cultivars were statistically analysed The results showed as follows Genetic and environmental variance, and heritability for every character have some difference regardless of the reaping times Dry fibre weight per stool, fresh bast thinkness, and ratio of fresh bast are important yield characters Due to the herdity of the characters relating closely each other, and the heritability and genetic progress existing certain difference, therefore the selection for every character should pay attention to other ones Meanwhile, besides of tradional method, other breeding method should carry out research for shortening breeding time in future
